AliOS Things中多语言交互性能优化（C与Python间相互访问）

项目描述

嵌入式领域中最早是使用汇编语言进行编程，但汇编语言入门门槛很高；C/C++的出现降低嵌入式领域入门门槛的同时也提高了开发效率。和C/C++开发相比，Python的开发门槛更低，开发效率更高。但Python语言并不能直接操作硬件，所以Python语义需要经过Python引擎的翻译转换成对C/C++语言或汇编语言实现API的调用才能运行。 本项目则是对C和Python的双向通信进行优化，如下题目可以任选其一进行优化：

1. Python到C的优化：对Python引擎进行优化提高Python语句的运行效率
2. C到Python的优化：产生中断后C语言调用Python注册的回调机制优化，提高C到Python消息的传递效率
3. 使用Python不可避免的会占用更多的内存，请思考并调研Python引擎中内存如何进行优化

In the embedded field, assembly language was first used for programming, but the entry threshold for assembly language was very high; the emergence of C/C++ lowered the entry threshold in the embedded field and improved development efficiency. Compared with C/C++ development, Python has a lower development threshold and higher development efficiency. However, the Python language cannot directly operate the hardware, so the Python semantics needs to be translated by the Python engine into a call to the C/C++ language or assembly language implementation API to run. This project is to optimize the two-way communication between C and Python. The following topics can be selected for optimization:

1. Python to C optimization: optimize the Python engine to improve the efficiency of Python statements
2. Optimization from C to Python: After an interrupt is generated, the C language calls the callback mechanism registered by Python to improve the efficiency of message transmission from C to Python
3. Using Python will inevitably take up more memory, please think about and investigate how to optimize the memory in the Python engine
